What is Naucto?
===============

Naucto is a browser-based retro game engine that lets you create 2D pixel-art games using **Lua**.
Everything happens in your browser: draw sprites, paint maps, write code, and play your game -- all
in one place.

The engine renders on a **320 x 180 pixel** canvas using WebGL, with **8 x 8 pixel** sprite tiles.
It is inspired by fantasy consoles and designed to make game creation accessible and fun.

Your first game in 3 steps
==========================

Step 1: Draw a sprite
---------------------

Open the **Sprite Editor** and draw a small character on sprite slot ``0``. Each sprite is an
8 x 8 pixel tile.

Step 2: Write the code
----------------------

Switch to the **Code Editor** and type:

.. code-block:: lua

   function _init()
     x = 160
     y = 90
   end

   function _update()
     if key_pressed("ArrowLeft") then x = x - 2 end
     if key_pressed("ArrowRight") then x = x + 2 end
     if key_pressed("ArrowUp") then y = y - 2 end
     if key_pressed("ArrowDown") then y = y + 2 end
   end

   function _draw()
     clear(0)
     sprite(0, x, y, 1, 1)
   end

Step 3: Play
------------

Click the **Play** button. You should see your sprite on a black background. Use the arrow keys to
move it around.

That's it -- you just made a game!
